Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The main focus of this study is to determine the use of nicotine-containing products across the three experimental conditions. Subjects will be monitored to determine their continued use of assigned cigarettes, switching to other combusted and/or non-combusted tobacco, or cessation of all tobacco containing products.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a single site, single-blind, randomized trial with three experimental conditions tested for a period of 8 weeks: 1) Very low nicotine content (VLNC) cigarettes (0.07 nicotine yield) with access to combusted (except cigarettes) and non-combusted tobacco and medicinal nicotine products; 2) VLNC cigarettes with access to only non-combusted tobacco and medicinal nicotine products; and 3) conventional nicotine (CN) content experimental cigarettes (0.8 mg nicotine) with access to combusted and non-combusted products. This study will examine the use of nicotine-containing products across the three experimental conditions. Subjects will be monitored to determine their continued use of assigned cigarettes, switching to other combusted (e.g., little cigars, large cigars, pipes) and/or non-combusted tobacco products (e.g., conventional smokeless tobacco, snus for smokers, dissolvables, e-cigarettes, medicinal nicotine), or cessation of all tobacco containing products. Toxicant exposure across the three conditions will also be examined.

Eligible subjects will be provided very low nicotine content cigarettes and are told to use the product ad lib for 8 weeks. Subjects will complete questionnaires on demographics, smoking and health history, drug and alcohol use history, mood and perceptions of the study tobacco product. Biomarker samples will be analyzed for exposure levels of nicotine and tobacco-related toxicants.
